The 393 is another stroker combination, that uses a slightly longer 3.850" stroke for more displacement and low-end torque. Compression ratios ranging from low to high make this a versatile setup, available in a variety of performance levels.

This is the most robust stroker combination available, using a 4.000" stroke to arrive at 408 cubic inches. Due to the long stroke this combo makes monster torque, although at the expense of top-end RPM. Regardless it is still a great setup for street/strip applications where the RPM aren't extremely high to begin with. Applications range from low to medium compression making this a fantastic choice when paired with a supercharger!
